Audio Research LS-25 MK1 Owners

Hello,
I've just switched from an LS-3 to the LS-25 mk1. I enjoy the increased detail, transparency, etc., however the bass seems so weak by comparison. Interestingly, the bass is more detailed (delineated?) but just seems thin on some of my favorite recordings. I've switched to an aftermarket power cord with some improvement. Is this endemic to tubes vs. solid state or are there things that I could be doing that I've missed? Cryoed tubes perhaps? PS Audio P300 conditioner? Thanks in advance for any suggestions.

I had a LS-25 MK.I and found the bass response to be exceptional. Is it a new unit? Have the tubes settled in as of yet? Might get a bit fuller response after a couple of hundred hours on the tubes? Also you might try the Sovtek NOS 6H23 as a tube substitute, as I found that they improved performance of the pre-amp in all areas and are not too expensive.

Also a fuller/rounder (Shunyata?) A/C cord might improve things as well. Good Luck.
